The working principle of excavator is mainly based on the synergy of hydraulic system and mechanical structure. The core components of excavator include engine, hydraulic pump, control valve, cylinder and bucket. The engine provides power, the hydraulic pump converts the power of the engine into hydraulic energy, the control valve is used to adjust the flow direction and pressure of hydraulic oil, and the cylinder drives the bucket to perform various actions through hydraulic energy.
Specifically, the working process of excavator is as follows: Engine start: The power of excavator comes from powerful diesel engine, which provides the power required for the whole machine. Hydraulic system operation: The engine drives the hydraulic pump, which converts mechanical energy into hydraulic energy, adjusts the flow direction and pressure of hydraulic oil through control valve, and finally drives the cylinder and bucket to perform various actions. The extension and retraction of cylinder enables the boom, arm and bucket to complete operations such as excavation, loading and unloading. Operating lever control: The driver controls the various actions of excavator through the operating lever, and the swing of the operating lever makes the hydraulic system adjust accordingly, so as to realize various functions of excavator.
In addition, the design of excavator enables it to work stably on rugged ground. The crawler chain provides strong grip friction, and the track rollers play a role of fixing and supporting, ensuring that the excavator can operate stably on various terrains.
